This hose kit has been designed to cut out the cross over pipe work on the Vauxhall Astra GSI and can be used with a universal 70mm cone filter or a 1.9 CDTI airbox. The kit contains a direct route induction hose, a 16mm internal diameter Fluoro-lined breather hose, a 16mm stainless steel joiner and fitting instructions. The 1.9CDTI airbox requires no DIY modification when used with this kit, as the Astra GSI airflow meter (70mm) fits inside the airbox opening and clips in position. Please note that if you are planning to use a VXR airflow meter (80mm), you should purchace the VXR direct route kit and follow the same fitting guidelines as the VXR too.
Our silicone hose kit colour options (from right to left)(from bottom) are black, blue, red, orange, RS green, white, yellow, pink, purple, stealth grey, green and nitrous blue. See our hose colours page for more photos.
Our hose clip kits contain all the hose clips you need to replace the standard clips in your engine bay. Each kit is tailored to the your specific model, giving you exactly the right clips for you. We use JCS Hi Grip stainless steel hose clips in our kits, regarded universally as being the highest quality clip available in the market today.
Measurements for our silicone hoses, hose clips and accessories are provided as internal diameters, except for products where the overall or external diameter is the more important measurement, such as for blanking plugs or stainless steel hose joiners.
